LIQUID COOLER 0R RECETACLE.

To all Awhom it may concern:

Be itlinowii that l', LOUIS ZnLAZo, a citi. Zeni of the United States, residing at the city State of Missouri, haye invented a certain new and useful Improveinentin Liquid Coolers or Receptacles, of

ivhich the following is a specification, reference being' had to the accompanying draw.-

ingsyfoiniing a. partdiereot, 4in whichk Figure l is a longitudinal sectional view lthrough niy new liquid cooler or receptacle;

fFig. 2 is avertical sectional view, on the line i 2m2, Fig. l; and Iiig. is a detail sectional View on the line Fig. l. l This invention relates to a .new and iiseiiil iinpi'ovenieiit in liquid-coolers or receptacles,

" tlieobjects of iny invention being to provide y"thereof maintained the consunierwith. their vso a receptacle adapted particularly for cous; taining or holding sweet-milk, buttervniilk,

With this object in view, my invent-ion consists iii the novel construction of the sevthat my cooler or `ported upon a floor or vcasing 3, which' inner casing 3 is ere parts ot niy cooler or reeeptacle and in the novel arrange-nient and combination of tlie'sanie, all iis-will hereinafter be described andafterward pointedout in the claims.

lllhile my cooler or receptacle is particularly adapted, stated, for containing and cooling milk and cream, and has been here tot'ore used, and will be herein described, in that connection, yet it is to be understood receptacle might equally Well be used for containing and cooling other liquids or uids.

'in the' drawings. wherein like reference characters reifer to like parts' throughout the 'several views.y 'it indicates which is 'preferably cylindrical and which may be of sheet nieta] or any' other suit-able material, casing` l' being preferably sup other suitable place by means of' suitable standards 2 (partly shown).

Suitably' arranged "Within, and

spaced away from, said outer casing; l is an. inner troni which the inilk or generally' upon re- .a level with the an outer easing,

also prefer'- i ably cylindrical and which may also be of raeeiieii irai., iii, ieri,

A sheet inetal. or any other suitable material,

suitable Banged conneetingepieees or Z-bars -lf beine' iret'ei'abl i airaiiO'edA between and connected to said casings l and for obvious purposes. The said inner casing 3 is preter-` ably separated on `all sides from said outer easing` l, thereby providing a space, as at 5, extending completely space is adapted to be received and hold brokeiiice, as shown.

Pi'eicrably at or near its :torwai'd end,

therearound, in which casing- 3' provided with an inlet-opei'iing,

as at (i, and supported upon casing 3 and surrounding saidopening- 6 is a small section of tubing` oi' neck portion 7 having its loiver eilge preferably,flanged,outwardly, as at 8, and soldered oi.' otherwisesuitably secured to said casing. .lhisnecl portion 7, shown iii Fig. 1i`ts through an alining opening iu,

and extends slightly-above, ,easing l,r iiilet opening beingadapted to be closedV by a suitable cover Q 'ieiiiovably littiiig in' said iiecli-poiti0n 7 and hay overhanging poi-tion or flange l0.

Preferably 'at or as at. il, and supported upon casing 1 and surrounding.said opening 1l a sinall neckportion l2'havingr its lower edge preferably lianged outwardly, as at 13, and soldered ory otherwise suitably secured to said casina'.

The top ,ol-- iieeleportioii l2 preferably on top ol neeliqiortion i?. and inlet-opening' 11 is likewise adapted. to be closed by a suitable cover 14; removably lit.- tiiigyin said neck-portion 12 and having' preferably an over-hanging` portion or iange l5. l

The broken or chipped ice is delivered into said space 5 between easings l and 3 through said inlet-opening 1l, the ice being; deliyered and spread 4until said space is preferably completely filled and said inner casing 3 covered on all. .sides thereby, the ivai'eif from such icelbeing space whenever necessary or desired through a suitable faucet 16 mounted on casing land eoinniunficatin g with. said space.

The casing` 3 is adapted to hold or contain the niilk or cream, the' saine being delivered tliereiiito'through, iulet.-opoiiiiig 6 and to be drawn;oietalen tlc-5; troiiiwhenever desired throughtaffsuitable faucet 17 arianged on casing .1, and communicating with the inte rior of 'casing El., .The mill: or cream in casing-v ]'ireferably near its rear end, cas; ing` it is also provided with an iiilet-opeiiing,

drawn oli :troni said the top,

' oi'ighly mixed erably horizontally disposed in casing',

when the crank 26 is operated, said stirrer Q have heretofore empl "of butter-milk and . casing 3 thlagitator or stirrer end, is supported in a step-bearing 25 fixed to the' casing 3,

' or cream served .or

uniformquality stirrer 18as-w'ill tion on said standards 21 by means of arms oiggclips 2S, as shown particularly in Fig. 3. These arms or clips 28 are preferably hinged at one end to said standards 21, recessed in their-middle to fit shaft 19, and at their other end are provided with spring portions 28a adapted to snap over and releasably engage with portions 21il of standards 21. It will be observed that the diameter of inletopening 6 `is suliicient to permit the passage ,therethrough of vstirrer 18. Whenever, -therefore, it is desired to clean said stirrer -and associate parts,'c`ap 9 and shaft 24 are removed from position, gear-wheels 22 and 23 being thereby disengaged, spring-portions 255. released from engagement wit portions 21a of standards 21, and the stirrer 1S then readily taken from its bearings and removed from the casing through said opening 6.

ing 3 being surrounded by said ice, will'be cooled and protected from changes inthe surrounding atmosphere, the temperature of the milk onorea'm being maintained at a proper degree and the milk or cream thus preserved. As is well known, however, milk, K particularly butter milk, or cream, when .allowed to stand, will settle, that is, the heavier constituents or ingredients of the milk or cream will fall to the bottom and the lighter constituents or ingredients ,go tov and that themilk or cream, when so served or furnished to the consumer, will varyvin quality. In order, therefore, thatthe milk or cream may be agitated an'd t e several constituents or ingredients thoror intermingled before the is served, I have provided in 18. This stirrer 18 comprises al shaft 19 and a plurality of preferably perforated blades 20 l am aware that minor changes iny the ariixedly secured or arranged in any suitable -I rangement, construction, and combination of manner on said shaft 19. Stirrer 18 is prefthe several parts of my cooler or receptacle may be made and substituted for those herein shown and described without departing from the nature and principle of my invention.

milk or cream shaft l 19 being rotatably and preferably loosely mounted o n suitable standards 21 resting upon and secured to .said casing. Shaft 19 at preferablyits forward end is provided with a beveled gear 22 adapted to mesh with a beveled pinion 23 xedly arrangedon a shaft 24. Shaft 24, at its lower I claim and desire to secure by Letters Pat- -ent is: "t l 1...'ylheh` combination with liquid cooler coniprisngan outer casing and an inner casing arranged within and spaced from said l space being thereby provided and at its upper end has a outer casing, a

bearing in-cover9 and is provided with a Suitable Crank 26 having M1 Opefafng hmbetween said casings for ice to cool the liquid dleor knob .27. g contained insaid inner casing, 'of a stirrer 'Preferably the standards 21-areof such an adapted to agitate said liqui andthereby .present all portions thereof to the cooling action of said ice, tally arranged within` said inner casing below the horizontal center, and bodily rotatable in the lower half, thereof, and a vertically-disposedshaft `engaging `with said "stirre'r and ,adapted to rotate the same, said shaftbeing mounted atene en'd insaid inner casing and extendingto the exterior 'at'fits other end through said inner and outer cas- |ings; substantially as described.'

2. Thecombination with lv a liquid-cooler lcomprising an outer casing and an inner casing provided with an inlet-opening' and arranged within' and spaced casing, a spaee being thereby provided 'between said casin to cool the liquid for ice contained in sai inner casing, of a stirrer height and the blades 20 of stirrer18 are of 'such a width that saidblades, on the rotation of shaftV 19, .just clear theloweil inner surface of casing 3. Itwill thus be seen that,

18 will, throi'ighV the means stated, be ro-l tated, and the constituent-s or ingredients of the milk-.or crearr'i-Qlin casing 3 be thereby thoroughly mixedor intermingled, the milk furnished from my cooler or receptacle being fresh, cool, and of or thickness.` Through the milk orcrea'm in casing 3 by be clear, new `portions of the milk orcream will be presented to the coolingrv actionof the ice in space 5, whereby the milk or cream in casing 3 will be rapidly cooled and the temperature thereof maintained.- practically vuniform throughout.

oyed myA agitation of the new'cooler or receptacle principally in connection with the` sale of butte milk, andfrom experience can state it as a fact that by and through the employment of my'cooler or receptacle as described, the amount or number of gallons sold *has increased more than said shaft `thirtyfold.
